GRATE Specification of Letters Patent.

Patented July 16, 1907.

Application sitak Jury 1, 1903. semi No. 163,879.

To all whom it may concern:

Be it known that I, ARTHUR B. CLUNIEs, of the city of Rochester, in thecounty of Mom-oe and State of New York, have invented certain new anduseful Improvements in Grates; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the reference-numerals marked thereon.

My present invention relates to improvements in grate structures forstoves and analogous uses, and has for its object the production of agrate and support wherein the parts may be readily inserted and lockedin position to avoid displacement and which is also adapted to form anash chute.

Other features of novelty and advantage will be hereinafter more fullydescribed and pointed out in the claims hereunto annexed.

In the drawings Figure l is a plan view of a grate and support embodyingmy invention. Fig. 2 is a central vertical sectional view of the same,upon the line 2 2 of Fig. 1. Fig. 3 is a sectional view upon the Fig. 4represents a section upon the line 4 4 of Fig. 2, looking in thedirection of the arrow, Fig. 5 is a similar view upon the line 5 5 ofFig. 2, looking in the direction of the arrow, and Fig. 6 is a sectionalview of a stove showing the improved method of removably supporting thegrate and ash chute.

Similar reference numerals in the several figures indicate similarparts.

In the present embodiment of my invention, 1 designates the gratesupport, formed in any suitable manner, preferably provided with aflange 2 by means of which it may be supported within thestove or otherreceptacle beneath the fire pot. This support is removable, and may beshaped to conform to the contour of the stove or other receptacle and ispreferably made conical with its lower end slightly smaller than itsupper end the ash chute thus formed being of a depth to extend bothabove and below the grate supported therein. Supporting lugs 3 3,recessed, as at 4, are provided in the support to receive the lugs 5 5of the grate frame 6, to retain the latter in position and prevent itfrom lateral tilting. At the front of this support is formed a lug orprojection 7 upon which rests the extension or flange S of the gratering, a groove or recess 9 being formed therein to guide said extension.At the rear of the support, a similar lng 10, is formed, having a recess11 to receive the extension or ange 12 of the grate ring 6. These lugsor projections on the support l, and said extensions of the grate ringare preferably curved to permit rotary motion of the grate in ahorizontal plane. At the front of this support 1 is formed a ledge 13,and at the rear is formed an elongated slot 14, the pin-poses of whichwill hereinafter appear.

The grate ring 6 in the present embodiment of my invention is circularin general outline, and is provided with depressions 15-15 at the frontthereof and the depressions 1(3 16 in alinement therewith at the rear ofsaid grate ring, and in these depressions rest the trunnions '17 17 ofthe rotatable grate bars 1.8 18 arranged in the central portion of thegrate ring (i. The trunnions at the rear end of the grate bars 18-18extend through the horizontal slot 14 in the support l, in such manneras to permit rotary motion of said grate frame and also to hold thelatter on the lugs or projections while those at the outer ends of thegrate bars extend over the notched or depressed portion of the support1, as shown in Fig. 2 and they are provided with the intermeshing gearwheels 19-19 and one of said ends is made angular in cross section asindicated at 20, to receive a shaking handle by means of which the gratebars and the grate ring may be rotated. Thrust bearing collars 2l, 21,are provided upon the forward ends of these grate bars, to limit theirrearward movement and retaining lugs 22 22 are formed upon the grateframe to prevent the lateral displacement of said grate bars.

In the present embodiment of my invention, the extensions 8 and l2 ofthegrate frame pass beneath and form supports for the journals 17 17 of thegrato bars 18-18, as shown most clearly in Figs. 4 and 5.

In placing the grate in position, the grate ring 6 is so located withinthe support or ash chute that the lugs or members 3 3 will support thecorresponding extensions 5-5 of the said ring, and the members 7 10 willsupport the extensions or flanges 8 12 respectively of the grate in suchmanner as to permit a rotary movement thereof. The grate bars l8 l8 maynow be inserted from the top in such manner that the inner ends orjournals 17-17 thereon enter the elongated aperture 14 in the support,after which the grate bars are lowered until the journals thereon restin the depressions 15, l5 of the grate ring, the parts then occupyingthe position shown in Figs. 1 and 2.

A grate constructed in accordance with my invention consists of fewparts which are simple in form and capable of being easily made of castmetal. The tapering or inwardly extending sides of the grate supportform a chute serving to direct the ashes and dust dropping through oraround the grate into a suitable receptacle which may be located beneathit. By arranging the grate support so that it extends around the gratethe latter is held on suitable projections which are included betweenthe planes of the top and bottom of the frame thereby obviating theinconvenience either in securing the latter in position beneath the repotvor in removing or inserting an ash pan beneath the grate* Furtherthe ends of the grate bars projecting through opposite sides of theframe lock it against accidental displacement.

Moreover', by forming the support l in the shape of an ash chute whichis made separately and removable from the stove casing, the manufactureoi the stove will be simplified and cheapened, and When it becomesnecessary to repair or replace the chute or support this may be readilyand inexpensively accomplished Without the necessity of taking the stovecasing apart as this chute rests upon suitable projections Within thestove casing and is therefore easily removable.

I claim as my invention:

l. In a grate, a support adapted to be inserted in a stove casing andhaving a horizontal slot foi-med in its rear side, a grate mounted torotate in a horizontal plane within the support, said grate comprising,`a grate ring and rockinggrate bars mounted thereon, said bars beingprovided with extensions arranged to enter 'said horizontal slot of thesupport to prevent displacement of the grate parts.

horizontal slot and are thus adapted to limit the amount' l of rotationof the grate and to prevent displacement of the parts thereof.

3. The combination with the stove casing, of a support mounted thereinhaving substantially solid or imperforate inwardly inclined sidesforming an ash chute, therear side of the support being provided with anelongated horizontal aperture, inwardly extending lugs or projectionsformed within the sides of the support and between the upper and loweredges thereof, a grate ring mounted to rotate in a horizontal plane andresting upon said lugs, and grate bars carried by the said ringr havingextensions projecting into the aperture of the support for retaining thegrate bars and ring in position on the supporting lugs While permittinga rotary motion of the grate ring relatively to the support.
